The angles always add to 180°: A + B + C = 180° When you know two angles you can find the third. 2. Law of Sines (the Sine Rule): a sin (A) = b sin (B) = c sin (C) When there is an angle opposite a side, this equation comes to the rescue. Note: angle A is opposite side a, B is opposite b, and C is opposite c. 3. Law of Cosines (the Cosine Rule):

WebMar 25, 2016 · An included angle is the angle that is formed at the vertex of two adjacent legs (sides) of a triangle. Legs are adjacent if they connect at the vertex. The … WebTwo angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees. One way to avoid mixing up these definitions is to note that s comes after c in the alphabet, and 180 is greater than 90. 12 comments ( 68 votes) Upvote Downvote Flag more Show more...
